An accurate after-market boost gauge is a MUST any time you alter your stock turbo-system, even if you are not turning up the boost. Do not rely on your stock boost gauge... as a general rule they are inherently innacurate and become even more so once you start making modifications. Many ranges are available, such as: 30 In Hg/+15 PSI,30 In Hg/+20 PSI, 30 In Hg/+30 PSI, 0-35 PSI, 0-60 PSI, etc. PLEASE CLICK ON A BOOST GAUGE CATEGORY BELOW.
